1. Introduction to Dial-Up Modems A Dial-Up Modem is a device that enables digital data transmission over traditional telephone lines. It works by converting digital signals from a computer into analog signals suitable for transmission over the Public Switched Telephone Network (PSTN) and then reconverting them back into digital format at the receiving end. Dial-up … Read more
1. Introduction to Quadrature Amplitude Modulation (QAM) Quadrature Amplitude Modulation (QAM) is a widely used digital modulation technique that combines both amplitude and phase variations of a carrier signal to encode data. By modulating both amplitude and phase, QAM significantly increases the data transmission rate compared to other modulation schemes like Amplitude Shift Keying (ASK), … Read more
1. Introduction to Phase Shift Keying (PSK) Phase Shift Keying (PSK) is a digital modulation technique in which the phase of the carrier signal is varied according to the digital data being transmitted while keeping the amplitude and frequency constant. PSK is widely used in modern digital communication systems due to its improved spectral efficiency … Read more
1. Introduction to Frequency Shift Keying (FSK) Frequency Shift Keying (FSK) is a digital modulation technique in which the frequency of the carrier signal is varied based on the digital data being transmitted while keeping the amplitude and phase constant. This technique is widely used in radio communication, telecommunication systems, and data transmission over noisy … Read more
Amplitude Shift Keying (ASK) is a fundamental digital modulation technique used in data communication. In ASK, the amplitude of the carrier signal is varied according to the digital data being transmitted while keeping the frequency and phase constant. This method is widely used in low-bandwidth and short-range communication systems. ASK is one of the simplest … Read more
